Glycemic Index GI News 2007

2007-09-27 Newswise Medical News Glycemic Index Values are Variable

There are many factors that can influence the glycemic index of a food, says Lichtenstein. For example, a piece of white bread may have a high glycemic index but, if a person eats a slice of turkey and cheese with that bread, the effect of the multiple foods may result in a different glycemic index than if that person had eaten the white bread alone. Since most food is consumed as combinations during meals and snacks, there is a need to assess the significance of using glycemic index values determined on individual foods for food mixtures. Similarly, it is important to know whether the food consumed prior to a meal or snack alters subsequent glycemic response.

2007-11-06 Carbo: Good or bad - INQUIRER. net, Philippine News for Filipinos

The old classification categorizes them into simple and complex. This was modified into carbo with high glycemic index and those with low glycemic index. The latest measure is the so-called glycemic load, since glycemic index alone did not tell us how much carbo is contained in the food item. The glycemic load tells us both the amount of carbohydrates in the food, how fast they are absorbed and its impact on the blood sugar levels. Low glycemic index foods, in general, are the healthier ones, because they are absorbed more slowly and increase the glucose level more steadily, not rapidly and abruptly like the high glycemic foods are.

Alan Barclay, Acting CEO Glycemic Index Ltd. of Sydney Australia indicated "Were pleased with the developments from The Organic Beverage Company in pioneering Glycemic Index Testing in the carbonated and functional beverage markets". Dr. Alexandra Jenkins, Vice President, Glycemic Index Laboratories, Inc. of Toronto Canada who has been involved in research related to the glycemic index since its inception more than twenty years ago stated: "we are excited to see an increase in the awareness of the Glycemic Index in the marketplace and the efforts by industry, such as The Organic Beverage Company, to increase the availability of low GI products.

2007-12-29 American Chronicle: Low glycemic index diet

In order to realize the contribution of low glycemic index diet in causing weight loss, it is necessary to be aware firstly of the fact that what is actually meant by glycemic index. The term glycemic index refers to a particular form of measurement between the amounts of food consumed by an individual in terms of carbohydrates that would contribute suitably to an individuals blood sugar level. It is calculated that the higher the glycemic index, the more a person is endangered towards contracting fatal diseases. Obesity is known to make a person ore susceptible to high blood pressure and other ailments like diabetes and cancer. A high glycemic index endangers a person equally to these diseases and such diets are also responsible for increasing blood sugar kevels. Therefore, a low glycemic diet is considered to be the most

2007-11-29 FuturePundit: Insulin Resistant Diabetes Boosted By High Glycemic Index Diet

Researchers remain uncertain regarding exactly how diet, including carbohydrate intake, affects the development of type 2 diabetes, according to background information in the articles. Studies have revealed that the body absorbs carbohydrates from different foods at different rates. This leads to varying effects on levels of blood glucose and the hormone insulin, which converts glucose into energy. Foods high on the glycemic index, such as rice and other simple carbohydrates, cause a rapid spike and then a drop in blood glucose, whereas high-fiber foods tend to be lower on the glycemic index and have a more gradual effect. Some evidence has linked highglycemic index foods with the risk of developing type 2 diabetes.

None of the participants had diabetes. Using these criteria, the scientists had 8125 eyes to analyse. They graded the severity of macular degeneration on a scale of one to five, conducted food frequency questionnaires and calculated the dietary glycemic index, a number indicating the quantity of high-glycemic foods consumed, for each participant. After controlling for age, sex, education level, body mass index, alcohol consumption and other variables, they found that the higher the dietary glycemic index, the more likely a person was to have macular degeneration. Those in the highest one-fifth of the dietary glycemic index had more than a 40 per cent increased risk of significant macular degeneration than those in the lowest one-fifth. The amount of carbohydrate consumed was not correlated with disease, suggesting that it is only

2007-05-02 Checking your glycemic index

The glycemic index (GI) is a numerical scale used to categorize carbohydrate-containing foods based on which extent they raise blood glucose levels. High GI foods are rapidly digested and as a result blood glucose levels as well as insulin levels tend to rise just as fast. On the other hand, low GI foods are slowly absorbed therefore blood sugar levels and insulin release are maintained stable and gradual. Knowing this, it is evident that low GI foods are the better choice. These consist of foods such as whole grain sources, oat bran and other high fibre foods (i. e. pasta al dente, lentils, legumes, etc. ). Most fruits and vegetables and minimally processed grains such as oatmeal, long-grain brown rice, bulgur wheat and barley are also healthy choices. These foods prevent blood sugar and insulin changes from being extreme.

2007-12-05 American Chronicle: What is Glycemic Index

The Glycemic Index is a concept developed in the University of Toronto in 1981. The purpose of the Glycemic Index is to measure the effect carbohydrates have on blood glucose levels. The Glycemic Index is imperative for anyone who needs to monitor their glucose level due to diabetes or hyperglycemia. With diabetes reaching epidemic levels in the United States, the development of the Glycemic Index could not have come at a better time. Each year, more people are diagnosed with this potentially life threatening disease that can cause many serious complications. It is important for anyone with this condition to familiarize themselves with the Glycemic Index so they can empower themselves and learn which foods should be avoided.

Researchers, led by David Ludwig, director of the Optimal Weight for Life program at Children and rsquo;s Hospital in Boston, fed some mice with both high and low glycemic index diet. High-glycemic index food, including white bread, white rice, cereals and concentrated sugar, raised blood sugar quickly, while low-glycemic index foods, like vegetables, fruits, beans and unprocessed grains, raised blood sugar slowly. Glycemic index is a measure of how quickly energy contained in the food is absorbed by the body, producing a rise in blood sugar levels. High GI foods lead to sharp rises in blood sugar level and similar rises in insulin level, as the body releases the chemical in response.
